The Interagency Transportation, Land Use, and Climate Change Pilot Project utilized a scenario planning process to develop a multi-agency transportation- and land use-focused development strategy for Cape Cod, Massachusetts, with the intention of achieving a reduction in future greenhouse gas emissions and considering the potential impacts of sea-level rise on the region. This scenario was developed through a process of data collection, scenario development by a consultant and by regional and local government during a workshop, and scenario assessment. The outcomes of this scenario planning process will inform and support the region's long-range transportation planning and other related efforts, as well as the planning efforts of local, state, and federal agencies.
